Lip rubbing

Does anyone else do this? I like to take rough things - a toothbrush, say - and then rub it against my lips until I start to peel, then I pick off the peel and eat it. I've always rubbed things against my lips. When I pull my eyebrows out, I'll rub them against my lips but I won't eat them. Sometimes I'll just rub my finger along my lip until it's sore. Does this count as dermatillomania? I pull my eyebrows and leg hair, and pick at my nails and nose, but I haven't seen anyone who just rubs their lips. Please let me know if you do too!
